Alfred is 0.7 ounces at the beginning.
After one week had passed, he is 11% larger. 0.7 * 1.11
After two weeks, the dust bunny's size is once again 11% larger.
0.7 * 1.11 * 1.11, or 0.7 * 1.11².
From here you can see that each week the dust bunny's size multiplies by 1.11. (1 whole plus 11 percent) How many times it is multiplied can be expressed with exponents.
So a disc is a circle and the formula for the area of a circle is
so 3.14*6^2
=3.14*36
=<span>113.04
area=113cm^2</span>
Answer:
3(C + 5) = 7
Step-by-step explanation:
Let C = unknown number
The <u>sum</u> of a <u>number and 5</u>:
C + 5
<u>Three times</u> the sum of a number and 5:
3(C + 5)
Three times the sum of a number and 5 <u>is 7</u>:
3(C + 5) = 7
<u>To solve</u>
Use the distributive law: a(b + c) = ab + ac
⇒ 3C + 15 = 7
Subtract 15 from both sides:
⇒ 3C = -8
Divide both sides by 3:
⇒ C = -8/3
When an equation is balanced, the different ways that the
simulation indicates are as follows:
- Happy Face appears
- The scales are balanced
- Pictures show same kind of atoms in reactants and products
- Pictures show same number of atoms in reactants and
products
